DETAILED DESCRIPTION

An individual may lose their appetite to eat food for a variety of reasons. For example, an individual may experience a reduced appetite if the weather is hotter than the user is comfortable with. In another example, an individual may lose their appetite for food because they are traveling, crossing time zones or experiencing jetlag. Other examples for an individual experiencing a loss in appetite may include, a busy schedule, a changing lifestyle (e.g., moving from one home environment to another), side effects due to medication, mental health conditions, or other illnesses that the individual may not be aware of.

Typically, individuals may struggle with diets or other significant alterations of an individual's nutritional intake due to a lack of palatable options. Accordingly, it may be advantageous to increase a number of palatable options for an individual by providing food options that are determined to be correlated with positive memory association of the individual, thereby increasing the individual's appetite and the likelihood that the individual will receive critical nutrients to support normal physical and cognitive functions.

Embodiments of the present invention provide methods, systems, and computer program products for analyzing user information to generate appetite improvement information. Embodiments of the present invention identify factors that correlate to a user's positive sentiment and recommend recipes for meals that are based on the identified factors.

FIG. 1 is a block diagram of appetite improvement system 100, in accordance with an embodiment of the present invention. Appetite improvement system 100 includes central repository 110, analytic engine 130, computer system 140, and user information storage 150, interconnected by network 120. In this embodiment, central repository 110, analytic engine 130 and user information storage 150 of appetite improvement system 100 are each a part of separate computing systems connected by network 120. In another embodiment, a portion of such components may be arranged in one or more computing systems, such that any separate component is configured to exchange data between one another over network 120. Furthermore, such computing systems, including computer system 140, may be desktop computers, laptop computers, specialized computer servers, or any other computer system known in the art. In certain embodiments, the computing systems may represent computer systems utilizing clustered computers and components to act as a single pool of seamless resources when accessed through network 120. For example, such embodiments may be used in data center, cloud computing, storage area network (SAN), wide area network (WAN), and network attached storage (NAS) applications. In certain embodiments, the computing systems described herein represent virtual machines. In general, the computing systems described herein are representative of any electronic device, or combination of electronic devices, capable of executing machine-readable program instructions, in accordance with an embodiment of the present invention, as described in greater detail with regard to FIG. 5. In this embodiment, the computing systems are implemented in various cloud computing environments, as described in greater detail with regard to FIGS. 6 and 7.

Network 120 can be, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and include wired, wireless, or fiber optic connections. In general, network 120 can be any combination of connections and protocols that will support communications between central repository 110, analytic engine 130, computer system 140, and user information storage 150, in accordance with an embodiment of the invention.

Central repository 110 represents a storage component configured to store appetite improvement information generated from analytic engine 130 based on user information received from user information storage 150, as described in greater detail with regard to FIG. 2. In this embodiment, central repository 110 includes one or more data structures, tables or databases, such as a relational database for storing appetite improvement information. Appetite improvement information may be generated and populated in central repository 110 in real-time (i.e., as user information is updated and/or collected), in incremental, and/or batch operations.

Analytic engine 130 is a software component configured to process and analyze user information stored in user information storage 150 and generate appetite improvement information for storage in central repository 110. In one embodiment, analytic engine 130 may be a software component that is part of a multi-modal electroencephalogram data-collection and adaptive signal processing system configured to handle single or multi-user brainwave applications. For example, analytic engine 130 may have access to a table that identifies predefined characteristics of brain state that are associated with a positive user sentiment. In this example, analytic engine 130 may implement various analysis tools to interpret user behavior based on the user's monitored brain state, and determine whether the user's monitored brain state matches any of the predefined characteristics associated with a positive user sentiment.

In one embodiment, analytic engine 130 may be configured with other content analysis tools, such as a semantic analyzer, or a sentiment analyzer. For example, analytic engine 130 may include a web crawler to access social media information stored in, or operatively connected to (i.e., fed to), user information storage 150. In this example, analytic engine 130 may identify information that interests a user, by accessing web pages and other text content that the user shares, reposts, etc. Furthermore, analytic engine 130 may apply a weighting and/or ranking mechanism to identify which information that is the most interest to the user by determining the frequency of occurrences for the shares and/or reposts, or by using natural language processing to understand the tone and sentiment of the user (e.g., level of excitement, enthusiasm, etc.) for the shares and/or reposts. Accordingly, the information that is identified as the most interest to the user may be further processed and analyzed to identify factors of the information that correlate to a positive users sentiment, where the factors may include themes, subjects, objects, people, hobbies, activities, etc.

Computer system 140 represents a computing platform configured to monitor a user health information, and other physical interactions the user performs. As previously described, computer system 140 may be a desktop computer, laptop computer, specialized computer server, or any other computer system known in the art. In one embodiment, computer system 140 may be part of a configured to capture a user's facial expression in order to determine a correlation between the user's sentiment and any food that the user comes into interaction with. In another embodiment, computer system 140 may be part of a multi-modal electroencephalogram data-collection and adaptive signal processing system, where computer system 140 may include a headset or another sensor device configured to collect brain state information of a user. In yet another embodiment, computer system 140 may be representative of a device that is configured to monitor real-time biometric data, such as a heartrate, blood pressure, etc.

User information storage 150 represents a computing platform that stores, or has access to, a plurality of data received from various data sources, as described in greater detail with regard to FIG. 3. In one embodiment, user information storage 150 may be collected and filtered by analytic engine 130. For example, analytic engine 130 may access various data sources through user information storage 150 to obtain personal details of a user, social media interactions of a user, exchanges in emails/text messages/instant messages involving a user, health information of a user, schedule and other lifestyle information of the user, emotional feedback information (e.g., brain state data) of the user, and food intake information of the user. In this example, analytic engine 130 processes the user information to identify factors which correlate to a positive user sentiment. Analytic engine 130 may determine that user-posted images that include the user smiling may constitute as a positive user sentiment. Accordingly, analytic engine 130 may perform image analysis on images that include the user smiling to identify factors which may correlate to the positive user sentiment. In another instance, analytic engine 130 may process the user's personal schedule to identify possible activities that the user frequently participates in. For example, if analytic engine 130 identifies that the user frequently participates in rock climbing, then analytic engine 130 may flag rock climbing as a possible correlation to positive user sentiment.

The descriptions of the various embodiments of the present invention have been presented for the purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing form the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.

FIG. 2 is a block diagram of appetite improvement information stored in central repository 110 for appetite improvement system 100, in accordance with an embodiment of the present invention. In this embodiment, central repository 110 stores appetite improvement information including, recipe information 111 and personalized user information model 112.

Recipe information 111 represents a collection of information identifying recipes, their corresponding nutritional information (e.g., fat percent, amount of sugar, amount of protein, etc.) and corresponding properties (e.g., shape, color, taste, etc.). For example, an entry in a table of recipe information 111 may identify a food item, such as a peanut butter and jelly sandwich. In this example, the recipe for a peanut butter and jelly sandwich is stored in recipe information 111 as well as the corresponding nutritional information. Furthermore, properties of the peanut butter and jelly sandwich may also be maintained, such as relative levels of sweetness, bitterness, sourness, saltiness, and umami, as well as possible shapes (e.g., square, triangle, etc.), textures (e.g., soft, crunchy, etc.), and colors. In one embodiment, recipe information 111 is populated automatically, by applying natural language processing, semantic analysis, and other rule-based and machine learning techniques to a corpus of recipe, nutrition, and food property information. In another embodiment recipe information 111 may be modified by an administrative user of central repository 110. In one example, analytic engine 130 may use information stored relational databases of recipe information 111 to provide comprehensive profiles for various food items. For example, analytic engine 130 may provide a profile for apple pie, indicating that it is a sweet, golden-brown, round food item with a specific nutritional profile corresponding to a specific recipe.

Personalized user information model 112 represents a collection of information, correlations, and models generated by analytic engine 130 based on user information stored in user information storage 150. In this embodiment, personalized user information model 112 includes user sentiment information 113 and recommendation list 114. User sentiment information 113 represents information correlating a user's sentiment with food, properties of the food, and other factors (e.g., time of day, weather, settings, etc.). Recommendation list 114 represents a list of recipes (i.e., steps to prepare food) that is generated by analytic engine 130.

In an example embodiment, analytic engine 130 may process and analyze user information from user information storage 150 to generate user sentiment information 113. In another example embodiment, user sentiment information 113 may represent information used to identify various factors such as settings, objects, environmental conditions, hobbies, activities, times of day, and/or other factors that correlate to either a positive or negative user sentiment. If analytic engine 130 determines that a particular factor correlates with a positive user sentiment, then analytic engine 130 may identify the particular factor as a positive token and store the positive token in user sentiment information 113. In another example embodiment, analytic engine 130 may rank factors based on a strength of the correlation to a positive user sentiment, and if the strength of the correlations are above a specified threshold, then analytic engine 130 stores those factors with the high strength correlations as positive tokens.

In one example, analytic engine 130 may determine that if a user expresses a smile or other type of facial expression, then analytic engine 130 may correlate the smile or other type of facial expression to a positive user sentiment. Furthermore, information for the expressed smile or the other type of facial expression will be stored along with its determined sentiment correlation in user sentiment information 113. In another example, analytic engine 130 may determine that if a user responds to an email in an enthusiastic or positive tone, then analytic engine 130 may correlate phrases, expressions or words identified in the email to a positive user sentiment. In another example, a community gardening club may update their website with an award congratulating a particular user with the best gardener award. In this update, the community gardening club may include images that include the particular user smiling next to their prized garden. Accordingly, analytic engine 130 may analyze the images of the particular user to determine that the particular user is expressing a positive sentiment and further identify aspects of the image that are associated with the positive sentiment, such as flowers. In general, analytic engine 130 may perform image analysis, text analysis, natural language processing, semantic and sentiment analysis, as well as other types of rule-based and machine learning techniques to determine which factors correlate with either a positive or negative user sentiment and store this information in user sentiment information 113.

Recommendation list 114 represents a list of recipes and other details (e.g., preparation techniques, times of day to prepare the recipe, substitution ingredients, customized preferences, etc.) that is generated by analytic engine 130 based on processing and analyzing user sentiment information 113 and recipe information 111. In this embodiment, entries of recipes in recommendation list 114 are continuously updated based on changing user information stored in user information storage 150 and appetite improvement information stored in central repository 110. For example, if a flower is determined to a positive token correlating to a user's positive sentiment, then recommendation list 114 may include food items that are prepared to resemble a flower. In another example, if analytic engine 130 determines that a user is enthusiastic about a sport team based on text analysis, then recommendation list 114 may include food items that are prepared to include themes of the sports team (e.g., colors, visualizations, etc.).

FIG. 3 is a block diagram of user information stored in user information storage 150 for appetite improvement system 100, in accordance with an embodiment of the present invention. User profile 151 represents data describing a user's age, gender, job profession, and other personal details (e.g., geolocation). Social media information 152 represents a collection of information related to social media interactions. For example, social media information 152 may include blog posts, status updates, images, online profile information (e.g., activities, hobbies, etc.), frequently visited or checked-in locations, comments, and other information collected from various social media sources. Data exchange information 153 represents a collection of information related to other interactions performed on their personal device (e.g., computer system 140). For example, text content, images, metadata, and other information extracted from exchanges involving text messages, emails, instant messages, and other computer-to-computer interactions may be included in data exchange information 153.

Health condition and lifestyle information 154 represents a collection of information related to a user's physical health and any pertinent lifestyle information. For example, biometric data (e.g., a heart rate) may be collected by computer system 140 and stored in health condition and lifestyle information 154. Pertinent health condition and lifestyle information 154 may include information describing any major life event change (e.g., lost friends or family members, moved to a nursing home, etc.), weather changes (e.g., the weather is getting too hot), work schedules, stressful environments, and/or other personal related matters. Emotional feedback information 155 represents a collection of information related to a user's emotional health. For example, computer system 140 may be part of an EEP system that can monitor brain state data and determine a user's emotional state (e.g., feelings, emotions, conditions, etc.). Food intake information 156 represents a collection of information related to a user's eating habits. For example, computer system 140 may be configured to monitor and evaluate whether the user has reduced their food intake recently (e.g., whether a user eats less often or whether a user's food intake is getting less comparing to before).

In general, user information stored in user information storage 150 may be continuously updated based on the updates received by the corresponding information sources, and based on information monitored by computer system 140. For example, computer system 140 may monitor brain state data while a user eats a particular food item, and accordingly store the brain state data and identify the data as being associated with the particular food item. In another example, computer system 140 may capture a user's facial expression in real-time while the user eats a particular food item, and accordingly store the facial expression information and identify the information as being associated with the particular food item.

FIG. 4 is a flowchart illustrating operational steps for generating appetite improvement information, in accordance with an embodiment of the present invention. In this embodiment, the appetite improvement information includes user sentiment information 113 as well as recommendation list 114.

Analytic engine 130 prepares the user information (step 402). In one embodiment, analytic engine 130 may evaluate, validate, curate, transform and/or enhance the user information included in user information storage 150 prior to analyzing. Furthermore, analytic engine 130 may rely on rule-based and/or machine learning techniques to ensure that all relevant images, text information, audio files and metadata are in a usable format prior to analyzation. After the user information is prepared, analytic engine 130 generates positive tokens based on the user information (step 404). For example, analytic engine 130 may apply various analysis tools and reference predefined definitions of user sentiment, to determine which factors of the user information correlate with a positive user sentiment, as described above. Furthermore, analytic engine 130 ranks the correlations to the positive user sentiment, based on the strength of the correlation, and the highest ranking correlations are generated into positive tokens used in subsequent processing. In instances where user information updates are received, analytic engine 130 may also analyze and process the user information included in the corpus updates to create, generate or regenerate, positive tokens.

Once positive tokens are stored in user sentiment information 113, analytic engine 130 maps, or applies, the positive tokens to recipes stored in recipe information 111 (step 406). For example, analytic engine 130 may search recipes stored in recipe information 111 to identify food options that match, can be modified to match, include, or incorporate, the positive tokens stored in user sentiment information 113. In one example, a positive token for a user may be a baseball, and accordingly, analytic engine 130 identifies recipes in recipe information 111 that can be modified to incorporate a baseball theme, or be prepared such that the final food product is in the shape and resembles a baseball. Accordingly, any identified recipes are included in recommendation list 114 and subsequently displayed to the user (step 408).

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cognitive computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds). A cognitive computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.
